Lecture

Force on Moving Charges

Description

This lecture discusses the calculation of the force on a single charge moving in a magnetic field, deriving the force of Lorentz and explaining its direction based on the charge's movement. It then applies this concept to analyze the trajectory of an electron entering a magnetic field region, demonstrating how the force causes the electron to move in a circular path. The lecture concludes by solving for the angle at which the electron exits the magnetic field region, showcasing the practical application of understanding magnetic lenses in electron microscopes.
